We investigate the structure of the optimal maintenance policy for such a system by minimizing the expected total discounted cost over an infinite horizon.</p> 2010-07-08 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1264627939 http://rave.ohiolink.edu/etdc/view?acc_num=case1264627939 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
